Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed February 14, 1914. Serial No. 818,687.

To all whom it may concern:

Be it known that I, JOSEPH F. Ann STRONG, a citizen of the United States, and a resident of New York city, borough of Manhattan, in the county and State of New York, have invented a new and Improved l/Vindow Sash and Frame, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide means whereby the sashes may be reversed to present both surfaces of the same to the interior of a room: to provide a simplified construction to accomplish the above-stated purpose: to provide a simplified form of weather stripping for the structure: to provide means operable from the inside of the building only for releasing the swinging structure.

Drawings.-Figure 1 is a side view of a window sash and frame constructed and arranged in accordance with the present in vention; Fig. 2 is a detail view on an enlarged scale and in section, the section being taken on the line 22 of Fig. 1; Fig. 3 is a detail view in elevation showing a fragment of a window sash and frame therefor, the sash being lifted to expose the locking member in the parting strip for the sash; Fig. 4- is a detail view on an enlarged scale, showing in vertical cross-section a fragment of the window frame and sashes mounted therein, one of said sashes being shown in partially rotated position; Fig. 5 is a vertical cross-section on an enlarged scale of a window frame and the sashes therefor, said sashes being constructed and arranged in accordance with the present invention; Fig. 6 is a detail view on an enlarged scale, the section being taken on the line 6-6 in Fig. 4; and Fig. 7 is a detail view on an enlarged scale, showing the junction of the parting bead provided for sashes constructed and arranged as herein disclosed.

Description-As seen in the drawings, the invention is peculiarly adapted to windows having two sliding sashes commonly known as upper and lower sash windows. As seen best in Figs. 2 and 6 of the drawings, each of the sashes is provided with an auxiliary side strip 12. The side strips 12 are each furnished with a groove 18,wherein when in service, a sash or weight' cord is disposed. Each strip 12 provides a bearing for the gudgeons 1%, on which the lower sash 15 and the upper sash 16 pivotally swing. As usual in sashes of this character, the parting rails thereof have correspondingly inclined surfaces 17 and 1S respectively.

The opposite vertical stiles of the sashes have an inner stop bead 19, an outer stop head 20 and a parting bead 21. Between these beads and strips are the runways 22 and 23 in which move the said strips 12 and the sashes 15 and 16 mounted thereon. The lower half of the stop bead 20 is removed as best seen in Fig. 1 of the drawings, the upper section presenting a squared shoulder 2%. The said stop head 20 is cut away flush with the inner surface of the bead 19, as shown best in Fig. 6 of the drawings. The parting head 21 is similarly cut away at the lower section thereof, but at a point below the shoulder 21, the object being to permit the sashes when lowered to swing under the full section of the bead 21, but not to swing completely on the pivot at this point. The abridged section of the head 21 is in service supplemented by an added section 25, which as best shown in Fig. 6 of the drawings, overlies the abridged section to form a guide and support for the stiles 26 of the sashes 15 and 16. The joints formed between the parting bead 25 and the stiles 26 of the said sashes are protected against weather by the metal weather strip 27, with which the said beads 21 are faced, the metal being secured to the body of the beads by nails or other fastening devices 28. The weather strips 27 are mounted on both the upper and lower sections of the parting bead and in the lower section to the auxiliary sections 25 thereof, as shown best in Fig. 6 of the drawings. The stiles 26 of the sashes are provided on the sides adjacent to the parting beads, with grooves to receive the weather strips. lVhen thus constructed a weather-tight and otherwise well constructed window frame and sash are produced, the sashes whereof are guided in their movement by the strips 12 and are balanced as in the conventional construction, by weights suitably mounted thereon.

The sections 25 of the strips 21 at the opposite sides of the sash are hinged adjacent to the sill thereof and swung outward over the said sill to lie prone thereon, as seen best in Figs. 4 and 5 of the drawings. Then the sections 25 are thus disposed, it Will be face of the window panes or sash. In this manner, it is possible to clean the window without leaning or passing to the outer side thereof. /Vhen after cleaning, the sashes are'raised to the upper reaches of the runways 22, the sections 25 are lifted to the upright position and are there secured by bolts 29, the holes for which are provided in the upper sections of the beads 21, while escutcheon plates 30 are mounted in the sections 25 adjacent to the upper and beveled junction end thereof. The heads 31 of the bolts are held below the surface of the escutcheon plates 30 to avoid obstructing the run of the lower sash l5. l/Vhen the sash 15 is lowered it normally covers the junction of the upper and lower sections of the parting beads 21-25 and the escutcheon plate 30. Thus it will be seen that when the sashes are locked in closed position, the means for operating the bolts 29 are covered by the said lower sash, making it difficult to remove the said bolts without detection.

The operation of the sashes when constructed and arranged in accordance with the present invention, is as follows: When it is desired to clean the windows, the sash 15 is first raised to its limit in order that the plate 30 and the bolt head 31 may be exposed. The heads 31 are then withdrawn from engagement with the beads 21 and the sections 25 are folded upon the sill of the sash, as shown in Figs. 4: and 5 of the drawings. The sash is now free to be rotated upon its gudgeon 1e, as shown in Fig. at of the drawings. after the cleaning operation on the lower sash is completed, it is straightened and adjusted to the weather strip on the side of the bead 21 in the upper section thereof and raised to its lifted position. The upper and outer sash is now drawn to the lowered position where the manipulation of this sash is the same as that described with reference to the lower sash. After cleaning, the upper sash is raised to the elevated position in the same manner as that above described with reference to the lower sash, and the sections are swung in their vertical or service position, when the bolts 29 are found to register with the holes pro vided in the lower end of the beads 21 and are there shot. The lower sash is now lowered to its normal position and if necessary locked, when it will be found that the window is thoroughly closed.

Claim: 1

In combination, a window frame having a plurality of parallel runways; a parting bead separating said runways; a plurality of sliding strips mounted'in' said runways and extending therefrom flush with said parting bead; a plurality of window sashes pivotally supported by said sliding strips, said sashes having disposed in the stiles thereof vertical grooves formed in the adj acent surfaces of said sashes; a plurality of perinanentlj' -attached half-length weatherstrips mounted on said parting bead, in the upper half-section thereof, said weather strips having laterally-extending flanges to fit said grooves; a plurality of removable weather-strip sections, each having laterallyextending flanges to aline with the flanges of the permanently-attached weather-strips; and hinges for securing said removable weather-strips at the sill of. said window frame.

In witness whereof I have signed my name to this specification in the presence of two subscribing witnesses.
